' Applimion ned December 6,1904.. semi No. 235,690.

To cir/ZZv whom it may @o7/warm' Be it known that I, JOSEPH D. COUGELIN,a citizen of the United States, resi'ding at Boston, county of-Sufl'olk,and State of Maslfor advertising purposes.

sachusetts, have invented an Improvement in Oorkscrews, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characterson the drawings representinglike-parts.-

This invention has for its obj ect to provide a novel corkscrew which ises ecially adapted eretofore, so far as yI am aware, corkscrews for thispurpose have been made of wire bent to form the head portion andcorkscrew portion, and usually a sheath of wood is provided into whichthe corkscrew portion may be inserted when the device is ,not in use.The advertising matter is usually placed upon the' outside of thesheath. v

' According to my present improvements I make the corkscrew of sheetmetal instead of wire and may make the device so that it not onlyconstitutes a corkscrew, but also is'constructed so that it can be usedto remove the crown-seals and loop-seals which are used for sealing somekinds of bottles, especially beerbottles. I

The blank from which my improved corkscrew is made is cut from a pieceof sheet metal, and the blank comprises a head portion and a taperingtail portion standing at an angle to the central line of the headportion, the angle being such that the corkscrew portion can be readilyformed by coiling said tail around the aXis of the finished corkscrew orlcentral line of the head.

In the drawings, Figure 1 illustrates one form of blank which I may usein making my corkscrew. Fig. 2 is one form of a completed corkscrew withthe sheath removed and shown in section. Fig. 3 is a section on theli'ne a a., Fig. 2. Fig. 4 shows apblank for ymaking another form ofcorkscrew. Fig, 5

shows a corkscrew made from said blank, and Fig-6 is an end view of Fig.5.

The blank shown in Fig. 1 is cut from sheet metal, and the die is soshaped as to cut a blank with the head portion 3 and the tapering tailportion 4. The central line of the head portion is the dotted line a a,and the tailportion of the blank stands at anangle to this central line.The corkscrew portion 5 is formed by coiling the tail about the centralline a a as distinguished from merely twisting the tail portion aboutits central line. I prefer to make the head portion 3 with a centralaperture 7, which h as the substantially iiat side 8, and the die usedincutting the blank will make the blank with a thin edge along the fiatside 8, as best seen in Fig. 3. The blank is also preferably providedwith a pointed tip 9. The thin flat edge 8 is constructed for removingthe ordinary crown-seal which is used in closing most beer-bottles, andthe pointed tip 9 is constructed to remoye, what is commonly known asthe loopsea Where the corkscrew embodying my invention is used foradvertising purposes, I prefer to associate with it a sheath 10, of woodor other similar material, on .the outside of which theadvertisingmatter may appear. Since the blank is cut from sheet metal, the sides ofthe head of the completed corkscrew are flat, and these flat sidespermit me to .place thereon' suitable advertising matter.

With the old-style corkscrew made of wire the advertisement appears onlyon the sheath, and therefore ifv the latter is l'ost the corkscrewitself has no value as an advertisement. With my improved device lsincethe advertisement appears on the corkscrew as well as the sheath theloss of the sheath will not completely destroy the device as anadvertisement.

The blank shown in' Fig. 4 is adapted to be formed into the corkscrewshown in Fig. 5, and the corkscrew shown in said figure has the tubularhead 10 and the corkscrew portion 5. The blank shown in Fig. 4 has therectangular head portion 1 l and the tapering tail portion 12 standingat an angle to the central line a a ofthe head portion. In making acorkscrew from this blank the head por-` tion is rolled into tubularform, as shown in Figs. 5 and 6, the edges 13 and 14 coming together,and thereafter the tail portion 10 is I-OO tion from which the corkscrewismade is ta- H pering in width, but is of uniform thickness, ecause thedevice is stamped from sheet metal. The corkscrew portion therefore hasy a uniform thickness throughout its extent, but is tapering in width.

The forms I have herein illustrated are 1 some which are preferred byme; but my invention is not necessarily limited thereto, as variouschanges may be made in the con struction and arrangement of the partswithout departing from the invention.

Having fully described my invention, what I claim as new, anddesiretosecure by Letters Patent, is-

1. A blank from which to make a corkscrew, said blank being stamped fromsheet metal and presenting a head portion and a tapered tail portionstanding at an angle to
